Chronic nodular panniculitis in a three-year-old mare.

This research article reports on a case of chronic nodular panniculitis in a three-year-old horse, which showed signs of both generalised steatitis and sterile nodular panniculitis, and was also found to have deficiencies in vitamin E and selenium.

Overview of the Research

The study describes a rare skin disorder, known as chronic nodular panniculitis, that was observed in a three-year-old mare. While the condition’s symptoms initially pointed towards sterile nodular panniculitis, further examination uncovered signs of both generalized steatitis (inflammation of fat tissue) and sterile nodular panniculitis. The assessment also revealed deficiencies in vitamin E and selenium in the horse.

Examination and Identification of the Condition

• The mare’s clinical signs consistently indicated the presence of sterile nodular panniculitis, a disorder characterized by recurrent or persistent inflammation of the subcutaneous fat tissue, leading to the formation of nodules.
• Upon histopathological examination, it was discovered that the mare was suffering from generalised steatitis as well as sterile nodular panniculitis. Steatitis, or panniculitis, essentially means inflammation of fatty tissue, and when generalized, it affects multiple or all areas of the body.

Nutritional Deficiencies

• The researchers also identified that the mare had deficiencies in vitamin E and selenium, two nutrients that are essential to a horse’s overall health.
• Vitamin E plays a pivotal role as an antioxidant, shielding the body from the destructive effects of free radicals, and in horses, it aids in boosting the immune system and helping with muscle function.
• Selenium, on the other hand, contributes towards the normal growth and fertility in horses and is involved in the protection of cells from oxidative damage.
• The deficiency of these nutrients in the mare might hint towards a possible link between nutrient deficiencies and the development of conditions like nodular panniculitis and steatitis.
